I just tried rev 211e47549b668c7cdd8658c0413a272f0d0495d4 (v2012.07-rc1)
for my PandaBoard. Sadly, this is failing when I try to use the onboard
ethernet (EHCI USB based) controller:
Sorry for the late response, at a conference. This is a known problem
and we will either have this fixed soon (Ilya Yanok is working on a
series) or we will build-time disable dcache support on these boards and
fix this properly for the next release.
In short, some cache clean-ups in ehci-hcd.c exposed other cache
problems on other platforms where our cache size is 64 not 32bytes.
I take it back, I forgot omap4 is 32byte cache. With the fix that
Tetsuyuki Kobayashi pointed you at (oh, and a Tested-by to that thread
if you can), can you please do a little stress testing of USB, to make
sure things are otherwise really happy (eth and perhaps a USB stick)?
Thanks alot!
Yesterday, this was working great. This morning, when I turned on
the board, it can no longer find anything on the USB bus - nothing at
all. This also applies to Linux when I boot from SD. I'm really
confused :-(
If I boot the board using the 2011.06 U-Boot, all is happy again.
It looks like the USB HUB (USB3320) seems to be stuck in reset when
I use the latest U-Boot.
Ever hear of any problems like this?
How about if you turn the dcache off at run or build time?
Sorry for being thick, but how do I do that? I don't see any
cache manipulation commands in 'help'
